Again, time to go to school:

The watermark is DIGTAL, not an actual visible water-mark the laser reads.  It's not so secret either: Verance Corp invented the audio watermark technology for licensing by manufacturers of Blu-ray and HD DVD players and components.  Audio Watermark, is part of the AACS content protection architecture that has been implemented by both HD DVD and Blu-Ray high definition formats. An inaudible signal chosen by content providers is inserted into the audio track of the content, and it is invisible to authorized users.   FURTHER PROOF that the data on both the BR-D and HD-DVD is the same, just a different format and package.  The watermark is an audio tone that the human ear cannot hear, but the technology in the unit can.  This is irrelevant to game discs.

Ok, that is for MOVIES, but we don't care about movies dude, people want the GAME DISC security hacked.  Game discs have security sectors no retail burner can make, but not convinced they have watermark in the game audio tracks.  Well, BR-D movies are being copied, so the watermark isn't all it's cracked up to be, is it?   Well, game discs are different than movie discs as far as SECURITY goes, so watermark, smartermark, bla bla, it's not what's holding PS3 hacking up.

Even if we assume it's possible to encode a watermark system into a song without damaging the playback sound in any way, and that it can be transmitted with its protection intact over both radio and analog, what's to stop someone from writing software to filter out the protection sequence? The idea of using algorithms to filter data is nothing new, its how audio formats like MP3 or Ogg work. While systems like Macrovision can only be bypassed via a physical device, or firmware hack that disables the copy protection, a computer has considerably more flexibility when it comes to its ability to edit, filter, and manipulate audio. In order to make such a watermark protect against any form of tampering, it would have to be impossible to write a computer program to de-filter the information. Of course, such an action is illegal under the DMCA.   AND still, nothing to do with GAME DISCS!

Seems like it's ALWAYS time for schooling.  People do not read up on the technology before they post about it, then they'd know it doesn't have anything directly to do with GAME discs.

Not only that Sony is calling it ROM Mark.

The Blu-ray content management system include three components.

Advanced Access Content System (AACS), which help secure content on discs with network and internet functionality.

Blu-ray specific enhancement for content protection renewability called BD+, which will be a programmable enhancement that will let content providers respond to organized attacks and update compromised code.

A unique and undetectable identifier embedded into movies, music, and games called ROM Mark to prevent mass production piracy and sale of unauthorized copies.
